OK, so I bring this up because I find working with matrices could potentially be very useful.
Watched a couple videos on how to put things in Reduced Row Echelon Form. The first video (https://www.khanacademy.org/math/li...ination/v/matrices-reduced-row-echelon-form-1) I watched ended up being over my head at the endish part of it.
The second video (https://www.khanacademy.org/math/pr...ination/v/matrices-reduced-row-echelon-form-2) I watched made a lot more sense.
But I still have a couple questions regarding what you can actually do to zero out or otherwise manipulate a matrix..
I know you can multiply a row by any real number (and divide as well I am assuming).
I also know you can add or subtract a row by another row.
I also know you can multiply (or divide) a row and then add or subtract that row from another row.
What I don't know, is if you can simply add or subtract a row by any real number.
I am also wondering if you can multiply by an exponent or square root a row. This implies that there are certain matrices with either exponents or square numbers in them and I am wondering how that works. Like can you put trinomials in matrix form and how would you solve them?
Basically I just want to know all the things you can do with Matircies to get to Reduced Row Echelon Form, so if there is a resource that talks about the rules about what you can do with matrices, I would like to see it.
